Common name: Axolotl or Mexican Walking Fish.
Scientific name: Ambystoma mexicanum
Description: Living up to an amazing 10-15 years the Axolotl is a hardy fresh water aquatic species, which grows generally 7-10 inches and sometimes up to 12 inches, native to Mexico which possess features typical of salamander larvae; External gills and a caudal fin extending from behind the head to the vent, but stay completely aquatic its entire life unless metamorphosis occurs. Metamorphosis is a rare occasion which can occur when water becomes extremely toxic/unbearable for the Axolotl to live in. Their heads are wide, and their eyes are lidless. Three pairs of external gill stalks originate behind their heads and are used to move oxygenated water. The external gill are lined with filaments (feather looking things) to increase surface area for gas exchange. External gills are used for respiration by pumping stored oxygen which they gather by gulping air from the surface to provide oxygen to their lungs. Axolotls have amazing regenerative abilities. if injured, even to the point of losing a body part, the Axolotl will heal/regenerate with full mobility within a month or two.
Common Colour Morphs: Wild type: Mottled green with shiny eyes and dark purple gills. Albino: White/very light pink with clear pink/red eyes and bright pink/red gills. Melaniod: Black/dark grey with black eyes and dark gills. Leusistic: White/pink with dark eyes(usually navy), bright red/pink gills. May or may not develop freckles. Golden Albino: Golden/yellow with shiny patches, pink/fire orange eyes, bright red/pink gills. Copper: Copper/olive with dark eyes, bright red/pink gills. GFP: (Green fluorescent protein) Is a recessive gene that can be contained in any morph. This means that those axolotl who carry the GFP gene can glow green under black/Blue light ( newer light fixtures come with this setting) Other morphs: There are other morphs that are considered rare and unique these morphs consist of Piebald, Golden Non Albino, Chimaerism and so on.
Tank size: Axolotls require 10 gallons each when adult size is reached.
Decor and hiding: One hiding place each, or one large enough to fit both, and couple of plants and rocks
